This invention relates .to oiling systems ro r internal combustion engines and has for its object to provide a system "having independent oiling means for the moving parts of the engine in" order that should a breakdown occur in one-of the oiling means: the

lubrication of the engine may still "beefliected. To this end a splash lubricating sys tem is provided supplied by a pump in the oil reservoir of the engine and a complete pressure oiling system is also provided. supplied by an independent pump from the reservoir. More particularly the pumps may be off the gear type and may be driven by the same drive shattand be contained in separate compartments I ing, means being provided whereby the out- }let of either of the pumps may be closed and reliance for the lubrication of the engine paced upon the otherpump. In order that the invention may be clearly understood and read i l y'carried into effect thelsame will now be describe l more erence to the accompanying drawing illustrating partly in verticalsectionandkpar-tly in side elevation, an'inte'rnal combustion .ennine in whic hthe -duzrl oilingsystem. is'applied.

Disposed within the crank shaft chamber 6 is the crank shaftd supported ina plurality of bearings 03 and adapted to actuate the connecting rods 6. ln tlie oil reservoir 0,

and preferably surrounded by a screen f is a housing 9 formed with separate chambers g, disposed one above the other but having a common inlet orinterconnection g whereby both chambers may be at all times and adapted to conduct lubricant from the pump chamber g to a plurality of oil troughs 6. These oil troughs are adapted lspi'ra l gear case the same -housfully with ref- The \vater jacket enclos'ingthe cylinders gears disposed to receive arms e which serve to splash the lubricant on the moving parts of the engine inthe usual manner. It will be noted that the conduit .71. a'ttter it leaves the last oil trough b is directed upwardly and connects with a lubricant manifold leading to *the at thefront ofthe engine in a manner which will be more fully described hereinafter. 'From the lowermost 'housing g the lubricant is conducted through the condui 1 :the main bearings d through the instnu- =1ne'nta1lity of a pluralityolf branch ducts "The connecting rod bearings 0 also receive --lubr1cant through this pressure system by ibrane'h passages d drilled in the fcran k shaft.

These two systems have no interconnection between them except that both of the gear pumps may,

if desired, be

driven by the same drive. shaft and may be contained in the same housing although in'separate chambers therein and have the same inlet. The outlet of either pump is controlled in order to permit the operation, of one lubricating system while the other is discontinued. Such a system. as has hereinbefore been described is particularly ad vantageous, in that, should a breakdown ocour in one system the other system will oper ate. A further important advantage resulting from the present improved oiling system is that the splash system torthe present day engine will. only operate satisfactorily up to, say 1,500 revolutions and when speeds higher than this are attained a pressure system is requisite in order to insure suiiicient lubrication at the crank shaft bearings.

Various modifications may be made in the form and disposition of the component elements going to make up the invention as a whole since changes in the form of the engine to which the system is applied may require a rearrangement of the illustrated embodiment and no limitation is intended by the foregoing description or illustration except as indicated in the accompanying claims What I claim is:

1. In a lubricating system for an internal combustion engine having a crank shaft and bearings therefor and gearing associated with the crank shaft, a reservoir for the lubricant, a housing for the gearing communicating with the reservoir, a housing disposed in the reservoir and formed with a plurality of interconnected chambers communicating with the reservoir, pumps disposed within the chambers of the second named, housing, respectively, a conduit to conduct lubricant from one of said chambers to the troughs and to the first named housing, a valve in said conduit proximate its point of connection with the chamber, a'conduit to conduct lubricant from another of said chambers directly to the bearings and to the first named housing, and a valve in said second named conduit proximate its point of connection with the chamber.

2. In a lubricating system for an internal combustion engine having a crank shaft and bearings therefor and gearing associated with the crank shaft, a reservoir for the lubricant, a housing for the gearing conr n'iunicating with the reservoir, a housing disposed in the reservoir and formed with a plurality of interconnected chambers communicating with the reservoir, pumps disposed within the chambers of the second named housing, respectively, a conduit to conduct lubricant from one of said chambers to the troughs and to the first named housmg, a valve in said conduit proximate its point of connection with the chamber, a conduit to conduct lubricant from another of said chambers directly to the'bearings and to the first named housing, a valve in said second named conduit proximate its point of connection with the chamber and lubricant cleansing means interposed in the second named conduit.

3. In a lubricatlng system for an internal combustion engine having a crank shaft and bearing therefor and gearing associated with the crank shaft, a reservoir for the lubricant, a housing for the gearing communicating with the reservoir, a housing disposed in the reservoir and formed with a plurality of interconnected chambers communicating with the reservoir, pumps disposed within the chambers of the second named housing, respectively, a conduit to conduct lubricant from one of said chambers to the troughs and to the first named housing, a valve in said conduit proximate its point of connection with the chamber, a conduit to conduct lubricant from another of said chambers directly to the bearings and to the first named housing, a valve in said second named conduit proximate its point of connection with the chamber, lubricantcleansing means interposed in the second named conduit, and f lubricant pressure indicating means connected with the second named conduit.

4. In a lubricating system for an internal combustion engine, a reservoir for the lubricant, two pumps in the reservoir disposed at different levels, separate outlets from the respective pumps, separate means to cause lubricant from the outlets to reach the same bearings, an inlet for the'lower pump below the surface of the oil in the reservoir, and means for causing the upper pump to take oil from the inlet of the lower pump.
